I To all whom it come'm:

Be it knohat I, ASHLEY G. Bnnn'm'r, a citizen ofthe United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Suction Cleaners, of which the following is a speci-i fication.

My invention relates tov suction cleaners and has for its object to provide a novel form of suction cleaner adapted to be operated by hand and embodying convenient and eii'ective apparatus for catching the dust and for discharging the same to the atmosphere.

More particularly, my suction cleaner em bodies a centrifugal cyclone dust collecting device mounted upon a wheeled truck having therein an electrically operated fan in combination with a yieldingly member having connection with e dust collector and through the dust collectorwith the fan, and detachable means for conveniently and readil discharging the dust which has been gat ered in the operation of the suction cleaner.

The full objects and advantages-of my invention will appear in connectlon with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the application of my invention, in one form,-

Fig. 1 is a side elevation oi? a suction cleaner embodying my improvement. Fig. 2 is a top plan view thereof. Fig. 3 is a sectional plan view of the cleaner member, and Fig. 4; is a sectional elevational view oi the cleaner member.

As illustrated, my cleaner comprises a motor box mounted upon wheels 11 which are journaled on studs 12 extending outwardly from brackets 13 connected to the bottom of the motor box. The fan casingl iis secured to the front of the motor box and 'fcomprises a central inlet case 15 and a side discharge opening 16. From an a'ngularly disposed extension 17 of the inlet case 15 extends a pipe 18 which passes through the 3 center of a conical top 19 formed in connection with cylindrical casing 20, the extended portion 210 of the pipe 18 being shown in Fig. 4. Pipe members 21 and 22 are secured b threaded nuts 23 to the sides of the cylin rical casing and united at 24 in a single pipe member 25 which goes to an elongated suction head 26 having the usual suctign slot therein and supported by sitigp orted rollers 27. .Members '21, 22, 25, together other articles which it is" desired to clean.

As best shown in Figs. 3 and 4, the members 21 and 22 communimte through the interlor of the nuts'23 with troughs 32 spirally arranged within the cylindrical casing 20 so as to provide spiral passagewa s 33 wh ch are closed at their upper en as indicated at 34 and which discharge tangentially in opposite directions at the bottom, as indicated in dotted lines at 35. Connected to casing 20'is a conical extension 36 supporting an upwardly extended cone 3?, the apex of which passes through the plane of discharge from passageways 33 within the chamber formed by casm 20. The space below the cone 37 is divide into four vertical passageways by partitions 38 and 39 .and the member 36 terminates in a threaded opening 40 to wh1chis removably secured a receptacle or jar fill. The casing 20, and assoc ated parts, is not only supported by the pipe 18 but also by a brace member 42 which secures the casing rigidly to the tan inlet case 15 on the front of the an cesing it.

the cleaner and through spiral passage 33 where the dust is precipitated by centrifugal action through the apertures about the lower edge of the cone 37 passing into removable receptacle 4:1. The very finest dust will encounter the bames formed by the trou h members 32 and will move outside of t e depending pipe section 210 with the result that such fine dust will ultimately gravitate downwardly and p-ass'to the container t1. The container 41 may readily be removed I Mtmtt through the cleaner and fan casing 1 at any time and its contents emptied. The operation is as simple as the emptying of a dust pan and does not involve either trouble.

devices. No strainer at all is used in the construction of my invention herein de scribed and the air at all times flows freely an discharges from the o n vent 16. T s insures the maximum ow of air to a given amount of power and uniform working conditions. r

I- claim: v a 1. A suction cleaner for carpets, rugs and the like comprising a pair of chambers having integrally united walls, one ofwhich is vertically cylindrical, and having means connecting the top of the vertical chamber with the other chamber, a tubular arm connected to the upper portion of the vertical chamber, a suction head on said armdiaving means engaging the floor so as to sup-' port the front end of said casing and having communication through the arm with the interior of the vertical chamber, means in the other chamber for inducin a current of air to pass through the suction cad, arm,

vertical chamber and other chamber and to 'the like comprising a pair of chambers having integrally united Walls, one of which is vertically cylindrical, a pair of tubular arms uniting with a single arm so as to form a yoke which is pivotally connected at its ends to the upper portion of the vertical chamber, a suction head on the prolongation of the united portion of said arms havin means 5 engaging the floor so as to support t e front. end of said casing and having communication through the arms with the interior of the vertical chamber,- means in the other chamber for inducing a current of air to pass through the suction head, arms, vertical chamber and other chamber and to discharge therefrom to atmosphere, and means in the vertical chamber for causing gravity separation of dust carried by said induced current. v v In testimony whereof I hereunto affix my signature.
